To all whom it may conccm:

Be it known that I, Cannons B. HsLnsnsN, a citizen of the United States,residing at Aurora, in the county of Cloud and State of Kansas, havemade certain new and useful Improvements in Automatic Pump-Couplers, ofwhich the following is a specification.

My invention is an improvement in automatic pump couplers, especiallyadapted for use with wind mills, and consists in certain novelconstructions and combinations of parts as hereinafter described andclaimed.

In the drawing Figure l is a side elevation of my improvement. Fig. 2 isa top plan view. Fig. 3 is a section on the line 33 of Fig. 1. Fig. 4 isa detail perspective view of the lower end of the brace. Fig. 5 is asimilar view of the coupler head, and Fig. 6 is a similar view of thesliding frame. Fig. 7 is a section on the line 7-7 of Fig. 3.

In the present embodiment of my invention, a coupler head A comprising acasing a having open ends a, is provided upon its sides with grooves ordepressions a in which is bolted the mill rod B, the said rod beingforked at its lower end. The space between the sides of the casing iscrossed by a partition a dividing the interior of the easing into twolongitudinal passages, a relatively wide front pamge a" and a relativelynarrow rear passage 0". The forward edge of the easing is provided witha socket a, and below the socket is a plurality of notches a all for apurpose to be hereafter described. A brace 11' is slidably mounted inthe rear passage, and the lower end of the brace is adapted to becoupled to the pump piston a in any suitable manner. The casing a is ofsudzl a length that the brace a is at no time entirely withdrawntherefrom, the brace thus serving as a guide for the casing whereby toretain the mill rod and the pump piston in substantial alineinent witheach other.

A coupling lever C is pivoted to lugs a upon the front face of the bracea near the lower end thereof, and the said coupling lever is providedwith an angular portion c adapted to engage the socket a when the casingis in proper position. The upper end of this lever is normallymaintained in separated relation with respect to the brace a by means ofa spring a secured at one end to the brace and resting at its other endagainst the coupling lever. Plates (2 are secured upon each side of thebrace a near its junction with the coupling lever, and the forward endsof the plates project upon each side of the coupling lever whereby toguide the coupling lever and to retain the spring in its properposition.

A pump head comprising a ring c is adapted to be secured to the top ofthe pump in any suitable manner, aud'the said ringis provided with anintegral upright am e having an angular portion c extending beneath thecoupler head and slotted to permit the pe of the brace a and thecoupling lever C. A swinging lever c is pivoted to 2 lug c" upon thefront of the ring, and upon the upper end of the swinging lever ispivotally mounted the pump handle D. The pump handle D is forked as atd, on the outer side of its connection with the swinging lever, and thatportion upon the outer side of the fork is grooved upon its under faceas at d. A sliding frame it is mounted upon the brace a" and the uprightarm 1:, the said frame being provided with longitudinal slots d', 11upon each side between the arm and the brace, and with a friction rollerd upon the outer side of the brace and engaging the same, and the forkedarms of the handle are pivotally connected to the irame as at d. It isevident from the description that when the handle is manipulated, thesliding frame will be moved vertically on the brace and upright arm. Asecond lever E is pivoted between the forks of the pump handle D, and tothe inner end thereof is pivoted the end of a link a having journaledthereon in the free end, a friction roller 2, moving in the slots d oithe sliding frame d", and between the coupling lever and the upright arma. At a point on the coupling lever G adjacent to the plates 0, on thebrace a, is a notch c, which is adapted to receive the pivot bolt (1connecting the forked arms of the pump handle with the coupling lever 0,when the said frame is in contact with the said plates,

In operation, when it is desired to couple the pump handle to the pump,the lever E is moved toward the pump handle D until the said lever restsin the groove on the under face thereof. This movement pushes thefriction roller e toward the brace a, carrying the coupling lever C outof engagement with the socket a, and releasing the piston rod a of thepump from the coupler head A. Upon elevating the free end of the pumphandle, and still retaining the lever E in the beforementioned position,the sliding frame d is moved downward until the pivot bolt d rests inthe notch c provided therefor in the coupling lever. The pump handle isnow connected with the pump piston as long as the lever E is retained inits beforementioned position. Upon releasing the pump handle, thepressure of the spring 0 tends to move the coupling lever away from thebrace, and when the windmill actuates the mill rod B, and the couplerhead A, the angular portion of the coupling lever will again engage withthe socket 11, thus coupling the mill and the pump piston.

It will be evident from the description, that when the lever E is inposition against the pump handle, the motion of pumping willautomatically couple the piston rod and the pump handle, and that whenthe pump handle is released, the windmill will be automatically coupledwith the piston rod.

It will be noticed from an inspection of Fig. 1, that the angularportion 0 of the upright bar this provided at the and adjacent to thebrace a with lugs 0', against which the friction roller d of the frame(F is adapted-to rest when the pump handle is released from the pump.
